Im writing a research essay on balls of different mass falling from a fixed height onto the floor. Divided into two parts, I first vary the mass of the top ball and then for the next part I vary the mass of the bigger base ball. No I am using the general inelastic equation.. attached above and I...
What equation should I use to represent a 3 body inelastic equation .. two ball of different masses falling together and colliding with the stationary ground.
And any hints on deriving the two body equation shown below
So in short I am adding weight on the side of the ball .. as mass of the wieights is increased concentration of mass is distributed more... so I decreases. I am confused I don't understand the parallel axis theorm. An an increase in alpha would obviously mean an increase in spin velocity? Yes?
I = kMr 2
Where M is the mass of the flywheel, r its radius and k is its inertial constant.
Can I calculate my own inertial constant( a sphere + 4 disks around the sphere)
Thanks Help will be appreciated
Would the center of mass change?
What about moment of inertia ?
How can I link the increase in the added mass to the spin of the ball?
For a full sphere, I = 2/5 m r2
By adding two bulk wieight on either side am i changing the value for alpha?
What causes this "wonky" bounce, alteration in a ball's aerodynamics?
How can I explain it assuming let's say I add 200 grams on the two opposite ends of a ball (x axis) but they arnt exactly aligned ... will the ball rotate around the y axis? Adding weights causes the spin because area of the...
My Experiment consists of two balls of different masses falling together in the y-axis from the same fixed height.Im researching how mass of the smaller ball affects its rebound height. My method of adding mass however was very crude as I stuck weights on using tape. This surely altered the...
I've already done the experiment ...
My Hypothesis and experimental data don't match
I was looking for some potential errors that's all .. and I am sure the crudely attached weights affected my readings a lot? But how?
Im stuck with an IB extended essay I don't understand at all. :mad: I am investigating the relationship between the mass of two soccer balls and the rebound height the top ball reaches when both balls fall from a fixed height. My way of adding mass to the balls is pretty crude, some tape and...
The floor has a value of restitution? sounds very absurd !
Doesnt measuring the rebound height and orignal height of a bouncing ball measure the coefficient of restitution of the ball and floor.
I guess I have to be a lot more specific to get help. I have two soccer balls and let's say bouncing each of them independently i get two separate coefficient of restitutions for the two balls.

The elastic collison equation actually gives me the 9x theoretical velocity amplification I hypothesized, however I've already conducted my experiment ( I increased the mass of my top ball by adding weight making it eventually 5 times heavier than the orignally larger ball). I noticed a decrease...
